Complementary Code Keying

  • CCK
German: Komplementäre Code-Umtastung
Japanese: 相補符号変調

Communications engineering. CCK is a modulation type based on direct sequence spread spectrum (DSSS), modified so that a greater amount of data can be transmitted in the same time - up to 11 Mbps. For signal coding 8-Bit words are used, which have specific mathematical properties guarantying the signal recognition by the receiver in spite of noise and multipath interference.

CCK is applied together with DQPSK (Differential Quadrature Phase Shift Keying), OFDM (Orthogonal Frequency Division Multiplex) or PBCC (Packet Binary Convolution Code). In this case CCK is used for the header, DQPSK, OFDM or PBCC for the user data of the transmitted signal. CCK is applied for WLAN communication.
